Title: Process of colour photography
IPC: G03C7/30
Filed: 1934-11-10
Abstract: 451,699. Colour photography. MANNES, L. D., and GODOWSKY, L., Kodak Park, Rochester, New York, U.S.A. Nov. 10, 1934, No. 32445. [Class 98 (ii)] A photographic emulsion layer comprising a mixture of differently colour-sensitized grains is exposed to an object in colours, developed in an ordinary developer without fixing, re-exposed to uniform light of a colour which affects only one set of grains, and colourdeveloped to the minus colour, these exposure and developing steps being repeated for the remaining set or sets of grains, and the silver images produced by the developments being finally dissolved out as by Farmer's Reducer, leaving a multicolour image of dyed gelatin. In a two-colour process, a mixed emulsion layer of normal thickness is used, containing grains sensitized to orange-red as by pinacyanol or naphthocyanol, and grains sensitized to green as by pinaflavol. To reduce the effect of blue-violet rays, the layer is either exposed to the coloured object through a yellow filter, or the orange-red sensitive part of the emulsion is rendered less sensitive to blue-violet as by immersion in a bath of Indian Yellow, which may also contain silver nitrate. To preserve the balance of the two parts of the mixed emulsion, the blue-green sensitive part may also be treated with a silver nitrate bath. After exposure, the layer is developed to completion, preferably with a soft developer such as metol, glycin, or acid amidol, containing as little sodium carbonate as possible to produce minimum relief. Caustic alkalies in the developer are avoided. The layer is then exposed to uniform light and treated with a colour-forming developer yielding a blue-green image, such as one containing dimethyl-paraphenylenediamine hydrochloride with alpha-naphthol or indoxyl, or paraphenylenediamine hydrochloride with trichlornaphthol. After washing, the layer is exposed to uniform white or blue-green light and treated with a colour - forming developer yielding an orange-red image, such as one containing thioindoxyl or para-nitrobenzyl cyanide with dimethyl-paraphenylenediamine. The layer is washed and finally treated as with Farmer's Reducer to remove the developed silver images. A similar three-colour process is referred to in which a blue-green component is developed as above, and the other components are developed with a colour-forming developer containing diethyl paraphenylenediamine hydrochloride to which is added bromo-thio-indoxyl for the magenta component and benzoyl acetone for the green. U.S.A. Specifications 1,897,866 and 1,900,870 are referred to.

Abstract: 245,161. Bullinger, X., (Assignee of Bullinger-Werke, Bullinger & Co.). Dec. 24, 1924, [Convention date]. Pole-pieces; coils. -In a small generator such as a cyclelighting machine, the output is maintained substantially constant in spite of wide variations in speed by widening out the faces of the poles in the direction of the axis of the machine by means of magnetic strips. Fig. 2 shows the application to a magneto in which a stellate permanent magnet b rotates within a laminated multipolar frame c, on the poles of which the coils d are placed. The end laminae are bent out at e in planes parallel to the axis of the shaft, so as to extend the polar area and retain the coils on the poles. In the form shown in Fig. 4, plate clips f are placed over the laminated poles and their ends g are bent out after the coils have been placed in position. In alternative constructions, the coil bodies are made of thin iron sheet, or pieces of angle-plate are pushed between the coils and poles.

Title: Means for avoid separation and turbulence in fluids moving with respect to solid surfaces
IPC: B64C23/08
Filed: 1945-12-03
Abstract: 616,163. Reducing turbulence in fluid flow. GROUPEMENT FRANCAIS POUR LE DEVELOPPEMENT DES RECHERCHES AERONAUTIQUES. Dec. 3, 1945, No. 32681. Convention date, Jan. 19, 1943. [Class 4] [Also in Groups I and XXXII] In apparatus having surfaces in contact with a fluid in relative motion, rollers or rotors are placed at those points where turbulence and separation of the fluid tend to be produced, the rollers or the like being driven so that their peripheral surfaces move in the same direction as the fluid, their surfaces also projecting slightly into the fluid, at least with respect to the downstream portion. Fig. 9 shows the invention as applied to the diffuser sections of a wind or water tunnel, pairs of rollers 14, 15, 16, 17 being mounted at those points where the angle of the diffusers changes abruptly. High pressure fluid may be discharged over the surface of the roller through slots such as indicated at 22, or drawn through a clearance space 20 between the roller and wall. The rollers may be provided with paddle wheels driven by the moving fluid. The Specification as open to inspection under Sect. 91 also describes an arrangement, Fig. 10 (Cancelled), in which a roller 24 is carried by a high lift flap 22 mounted on an aircraft wing 21, the surface of the roller projecting above the upper aerofoil surface. This matter does not appear in the Specification as accepted.

Title: Improved thermoelectric device and method of forming same
IPC: H01L35/26
Filed: 1961-09-12
Abstract: 972,368. Thermo-electric devices. GENERAL DYNAMICS CORPORATION. Sept. 12, 1961 [Sept. 20, 1960; Aug. 14, 1961], No. 32773/61. Heading H1K. A non-rectifying contact is made to a semiconductor material with a high thermo-electric figure of merit by bonding a member at least the surface material of which is insoluble in the semi-conductor to it using a doping material characteristic of the conductivity type of the semi-conductor and having a lattice constant within 15% of a lattice constant of the surface material of the member. Contacts of this type may be made to lead telluride, bismuth telluride or zinc antimonide of N or P type using contact members with thermal expansion coefficients close to those of the semi-conductors. In a typical case a nickel foil 1 mil. thick coated with copper 0.5Á thick is heated coated face downwards on the end of a block of N-type lead telluride 2.5 mm. long to 600 C. in a reducing atmosphere. Alternatively, a copper foil 1 mil. thick, with a 5Á coating of nickel and an overlying coating of copper 0.5Á thick is used. Heating is in this case effected by preheating a graphite rod and then placing it on the uncoated face of the copper foil. Similarly, a contact to P-type zinc antimonide is made by coating a 1 mil. thick nickel foil with 0.5Á of silver through the intermediary of a copper film 0.01Á thick, assembling it with the silver layer on the zinc antimonide and heating to 600 C. The coatings may in all cases be formed by vacuum evaporation or electroplating. A number of semi-conductor bodies with contacts 12, 14 (Fig. 1) of different sizes formed at both ends in this way may be soldered or brazed between two plates 26, 28 through apertures 30 in plate 28 to form an assembly from which any body may subsequently be removed without disturbing the assembly as a whole. The method also allows different semi-conductors used in the assembly to be contacted under different suitable conditions prior to being finally assembled.
Patent GB-896392-A (GB)
Title: Improvements in the recovery of lithium from solutions containing both lithium and aluminium
IPC: C01D15/00
Filed: 1958-10-14
Abstract: Lithium compounds, especially salts such as the sulphate, are recovered from solutions containing both lithium and aluminium, by precipitating the aluminium as the hydroxide by suitable pH adjustment preferably to between pH4-pH12, separating the precipitate, heating it to at least 200 DEG C., and washing it to extract the lithium contained therein.  The process may be combined with the recovery of lithium values from ores containing lithium and aluminium which have been acid treated to solubilize the lithium, by mixing the precipitate with the treated ore, and calcining and washing the mixture.  Thus, in an example, lepidolite was ground and heated with 60 DEG B\'e sulphuric acid, and then calcined and treated with water to give solutions containing lithium and aluminium.  The initial solution, which is rich in lithium, is treated with calcium carbonate to precipitate aluminium hydroxide containing some of the lithium, and this precipitate is mixed with the next batch of acid-treated ore.  The solution remaining after the precipitation is alumina-free lithium sulphate.  The later solutions from the ore-washing, which are comparatively poor in lithium, are employed as wash liquors for later batches of acid-treated and calcined ore and precipitate.
